How to Appeal a Denied Health Insurance Claim in Houston

Step 1: Identify Your Plan Type

Determine whether your plan is state-regulated (fully insured) or federally regulated (ERISA self-funded). Check your insurance card or Summary Plan Description. If your employer "self-funds" the plan, Texas state consumer protections generally do not apply and your appeal is governed by ERISA (29 C.F.R. Section 2560.503-1). If you purchased insurance directly or through an ACA marketplace, Texas state law applies.

Step 2: Read the Denial Letter and Request Your Claims File

Your denial letter must state the specific reason, cite the policy provision relied upon, and provide appeal instructions. Request your complete claims file, including the clinical policy bulletin and the reviewer's credentials. For ERISA plans, you are entitled to this information under 29 C.F.R. Section 2560.503-1(m)(8).

Step 3: Gather Clinical Evidence and Your Physician's Letter

Assemble your medical records, physician's letter of medical necessity citing applicable clinical guidelines, and any peer-reviewed literature supporting your treatment. For Houston's major health systems (Houston Methodist, Texas Medical Center, Memorial Hermann), your physician's team is often experienced with insurance appeals and can provide strong supporting letters.

Step 4: File the Internal Appeal

Submit your appeal via certified mail and through the insurer's portal. Include all clinical documentation, your physician's letter, and citations to applicable clinical guidelines and federal or state law (Texas Insurance Code, ACA, ERISA as applicable).

Step 5: Request Independent Review (IRO)

After exhausting internal appeals, request independent review through the TDI's IRO process at tdi.texas.gov/health/irohmo.html. The TDI assigns an accredited IRO to review your case. The IRO's decision is binding on the insurer.
